Pressure Tight Sealing Plugs

STOPPERs are plugs which were developed for pressure-tight sealing of fibre cement and plastic distance tubes with an inner diameter of 22mm
High-strength plastic specially developed for this application
Temperature range -35°C to +70°C. If the plugs are installed at
ambient temperatures below 0°C, they must be stored above freezing
point beforehand for a better installation. All-weather installation
Just drive them in and they are tight
Little storage space required

Water

Since plastic and fibre cement distance tubes with a specified internal diameter of 22mm are subject to manufacturing tolerances, further extended tests were carried out at MFPA in Leipzig for an internal diameter of 21.5 to 23mm.

Fire

Fire resistance class El 120 as per DIN EN 13501-2 Room closure test with fibre cement distance tubes
For the duration of the test (120 minutes), no cracks or gaps
developed on the room side. During this time, no flames were visible on the side facing away from the fire
Construction material class DIN EN 13501-1 E = normally flammable
DIN 4102-1 B2 = normally flammable
